Yes - so far. I was a little preturbed the first couple of days because of the B&N servers and I had to figure out how to download from the computer since I don't have wi-fi. But now that I have a few books to read on it, I really like it. I like how the screen isn't glaring bright white. It looks like an actual book page. I do love the smell and feel of real books but I only have so much room for them.
My brother works for Sony Corp. and my dad has a Sony e-reader from him. When my dad called him to see about getting one for me, he said go with the Nook it is better than both the e-reader and the Kindle. Apparently that is because it can download different types of files?? I don't know if that is true. I also heard someone say that the Kindle is backlit so you can read in the dark, but for some people that can cause headaches.
